TVC IMAGING WITH NIRS-IVUS

The TVC Imaging System™ combines enhanced intravascular ultrasound (IVUS) with near infrared spectroscopy (NIRS) to detect lipid-core plaques suspected to be vulnerable to rupture and to cause fatal coronary blockage.

Each month a new case is presented demonstrating how NIRS-IVUS TVC Imaging provides clinical benefit.

    • CASE OF THE MONTH

    NIRS-IVUS TVC In Vivo Imaging Detects Findings Compatible with Neoatherosclerosis in a 7 Year-old DES with Restenosis, and Warns of No-Reflow

    A patient with a long history of CAD presents with an NSTEMI. ISR is detected and NIRS-IVUS TVC Imaging reveals unique findings compatible with neoathersclerosis. How can TVC Imaging aid in treatment of this high-risk patient?
